Manufacturing Processes is designed for a first course in manufacturing at the junior level in mechanical, industrial, and manufacturing engineering curricula It may also be appropriate for technology programs related to these engineering disciplines The book is based largely on my other manufacturing book, Fundamentals of Modern Manufacturing: Materials, Processes, and Systems That book is approximately 1000 pages long, and it competes with other manufacturing textbooks that are also very long Complaints are sometimes leveled that these books include more content than can possibly be covered in a one-semester course The counterargument to that complaint is that these very comprehensive volumes will serve as valuable references for students in their future professions, assuming those professions are related to design and/or manufacturing With this new book, we are attempting to provide an offering that is significantly shorter than the other texts (about 700 pages versus a thousand or more pages) To decide on the coverage of this text, John Wiley & Sons conducted a survey of faculty who have adopted the Fundamentals book or its competitors to determine which topics they considered most important in their respective courses Based on the feedback from that survey, we developed the topical content of the current book, which focuses on manufacturing processes Coverage of engineering materials has been reduced from eight chapters to two, and coverage of production systems has been reduced from five chapters to three The two chapters dealing with electronics manufacturing have been eliminated because our survey showed that many mechanical engineering instructors not feel the need to include this area in their courses Finally, there are several instances in which I combined chapters All of these changes have resulted in a new book that contains a total of 30 chapters, compared with 42 chapters for the fourth edition of the Fundamentals book The chapters on manufacturing processes are taken almost verbatim from Fundamentals In some cases, I have shortened the coverage by omitting certain processes or details about processes that seemed appropriate for the more comprehensive text but not for this introductory version The emphasis on manufacturing science and mathematical modeling of processes remains an important attribute of the new book Readers will notice that the Historical Notes and end-of-chapter Multiple-Choice Questions have been eliminated from the new book End-of-chapter Review Questions and Problems have been retained, but the number of problems has been reduced All of these changes have been made to reduce page count, which results in a textbook that includes most of the topics that are covered by most instructors who teach courses in manufacturing For instructors who require a more comprehensive treatment of the subject than is contained in this new book, we hope they will continue to adopt the Fundamentals book SUPPORT MATERIALS FOR INSTRUCTORS For instructors who adopt this book for their courses, the following support materials are available: å A Solutions Manual (in digital format) covering all problems and review questions å A complete set of Powerpoint slides for all chapters v FFIRS02 07/01/2011 vi 18:24:42 Page Preface These support materials and others may be found at the website www.wiley.com/college/ groover Evidence that the book has been adopted as the main textbook for the course must be verified Individual questions or comments may be directed to the author personally at Mikell.Groover@Lehigh.edu FFIRS03 07/01/2011 18:27:56 Page ACKNOWLEDGMENTS I would like to express my appreciation to the following people who served as participants in our survey that resulted in the decisions on content for this book: Yuan-Shin Lee, North Carolina State University; Ko Moe Hun, University of Hawaii; Ronald Huston, University of Cincinnati; Ioan Marinescu, University of Toledo; Val Marinov, North Dakota State University; Victor Okhuysen, California Polytechnic University, Pomona; John M Usher, Mississippi State University; Daniel Waldorf, California Polytechnic State University; Allen Yi, Ohio State University; Jack Zhou, Drexel University; and Brian Thompson, Michigan State University In addition, it seems appropriate to acknowledge my colleagues at Wiley in Hoboken, New Jersey: Executive Editor Linda Ratts, Editorial Assistants Renata Marcionne and Christopher Teja, and Production Editor Micheline Frederick Last but certainly not least, I appreciate the thorough efforts of editor Joyce Poh at Wiley in Singapore vii FFIRS04 07/01/2011 18:31:18 Page ABOUT THE AUTHOR Mikell P Groover is Professor Emeritus of Industrial and Systems Engineering at Lehigh
